What's a good cents-per-mile value?

1.5+ cents for economy, 2+ for premium economy, 3+ for business/first class. Anything below 1 cent is usually a bad deal unless you have miles expiring. Context matters — a 1.2 cent redemption on a flight you need is better than hoarding miles for a 5 cent redemption you'll never take.

Should I include the miles I'd earn on a cash ticket?

Yes, if you want precision. If a $500 cash ticket earns 2,500 miles (worth ~$37 at 1.5 cpp), subtract that from the cash price. Use $463 in your calculation instead of $500. Most people skip this for simplicity, but it matters on expensive tickets.

Do all programs value the same?

No. United miles are easier to earn and often value at 1-1.3 cents. Virgin Atlantic or Air France miles can hit 3-10 cents on specific premium routes. Don't compare cpp across programs directly — compare each redemption to its own cash price.

What if there's no cash price available?

Sometimes award space exists when cash seats are sold out, or vice versa. In these cases, cpp doesn't work. Focus on whether the miles price is worth it to you personally. If the flight would cost $1,200 and you're paying 40,000 miles, that's still 3 cpp even if no cash seats exist today.

Should I factor in transfer bonuses?

Yes. If you transfer points with a 30% bonus, you're effectively paying fewer miles. A 50,000-mile ticket costs you 38,462 points with a 30% bonus. Run your cpp calculation using 38,462 instead of 50,000 — your value just jumped from 2 cpp to 2.6 cpp.

How to Calculate Cents Per Mile for Award Flights

Divide the cash price of a flight by the number of miles required, then multiply by 100. If a $500 flight costs 25,000 miles, that's 2 cents per mile. Aim for 1.5+ cents per mile to make redemptions worthwhile, though break-even varies by program.

Find the cash price of your exact flight. Search for your specific route and dates on the airline's website or Google Flights. Use the total cash price including taxes and fees. Make sure you're comparing the same cabin class (economy to economy, business to business). Screenshot or write down the exact price.
Find the award price in miles. Search the same flight through the airline's award booking tool or transfer partner. Note the total miles required. Ignore any cash co-pay for now — we'll address that separately.
Run the calculation. Cash price ÷ miles required × 100 = cents per mile. Example: $450 flight ÷ 30,000 miles × 100 = 1.5 cents per mile. Use a calculator. Double-check your math.
Account for taxes and fees on award tickets. Award flights often charge $50-400 in taxes and fees. Subtract these fees from the cash price before calculating. If the cash flight is $500 and the award ticket charges $150 in fees, use $350 in your calculation, not $500.
Compare to your break-even point. Most programs: aim for 1.5+ cents per mile. Premium redemptions (business/first class): 2+ cents is good, 3+ is excellent. Economy: anything above 1.2 cents beats most credit card earning rates. Below 1 cent is usually not worth it unless you have miles expiring.
